FROG FOR RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 760,362, dated May 17, 1904.

Application filed February 17, 1904- Serial No. 194,087. (No model.)

To all whom it may concern:

Be it known that I, J OHN N. VVOLEINGER, a citizen of the United States, residing at Albany, New York, have invented certain new and useful Improvements in Frogs for Rail ways; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to railway-frogs,and is an improvement on all such as are known to me.

In the drawings, Figure 1 shows a plan view of my frog; Fig. 2, an edge view of the tongue; Fig. 3, a plan view of the covering-plate, and Fig. 4 a longitudinal View in cross-section of Fig. 1.

The numerals 1 and 1 show the rails, and 2 a cavity in the frog between them.

3 shows a narrow slot through the floor of the frog and under the tongue 2' in order that all water may readily pass out of the cavity and into the ground and not freeze in the cavity under ordinary winter conditions.

2 shows the rear end of the tongue lying in a cavity or recess 4, in which it moves sidewise enough to let the forward end of the tongue also move sidewise.

At 6 is seen a resilient device consisting of a bowed flat spring, preferably, which presses the tongue 2 against rail 1, as seen in Fig. 1, and at 7 will be seen another resilient device in the form of a flat spring, preferably, which assists spring 6 in so doing. At 5 is seen the recess in which spring 6 rests.

8 shows the covering-plate in Fig. 1 broken away, so as to show the working parts.

In Fig. 2 is shown an edge view of the tongue, showing that on its under side it has slight protuberances 2 upon which it rests on the floor of the frog and which leaves open spaces between them, their object being to first reduce the friction of the movement of the tongue and also to leave open spaces, so the water and dirt may enter and pass out of the slot The operation is as follows: As a car passes along rail 1 approaching the narrow end of the frog the flange of the wheel pushes the thinned end of the tongue aside and compresses both springs 6 and 7 and the car passes, when the resilience of the springs will throw the tongue back into its normal position again without manual interference, the friction of the tongue on the floor of the frog being reduced by the projections 2 The plate 8, lying over the base of the tongue 2", keeps the moving parts in place and protects them. As the tongue moves from side to side it scrapes the dirt out of the way and practically the most of it through the slot 3 and leaves no extraneous matter suflicient to cause any slowness of action in the tongue.

Having now described my invention, so that those skilled in the art will know how to make and use the same, what 1 claim, and desire to secure by Letters Patent, is-

1. In a railway-frog an opening in the bottom or floor thereof through which water and dust may escape; a recess in said frog arranged to receive the rear end of the tongue; a tongue having the rear end thereof lying therein and having a lateral movement; automatic actuating devices on each side of the rear end of the tongue and lying and operating in said recess and arranged to keep the tongue when not in use in its normal position and to return the tongue to that position when a car has passed; projections on the under surface of said tongue resting on the floor of the frog and a cover for the rear end of the tongue, substantially as described.

2. In a railway-frog, a recess in the body of the frog; a tongue having its rear end in said recess; automatic devices on each side of the rear end of the tongue in said recess arranged to move the tongue sidewise and a cover for the resilient devices and the rear end of the tongue substantially as described.

In witness whereof I aflix my signature in presence of two witnesses.

JOHN N. IVOLFINGER.
